When is the best day to book a flight?

If you need a plane ticket, you might get a good deal by purchasing on a specific day. Which day? Depends on where you get your info. For instance, according to Expedia's 2023 Travel Hacks Report, Sunday is the best day of the week to find cheaper flights—and has been for the past 4 years.1 Booking on a Sunday (compared to Friday) tends to save travelers an average of 15% on international flights.

There might be another good day to book airfare. "The best time to purchase airline tickets is generally on Tuesdays around 3:00 p.m. ET," says Justin Albertynas, CEO of Ratepunk, a browser extension that compares hotel price offerings, and co-founder of AirGuru, a flight comparison tool. Tuesday afternoon could be a deal sweet spot, Albertynas says, because many airlines might release new fare sales on Monday evenings. By Tuesday afternoon, other airlines might attempt to match the lower prices to compete.

You could let the above be your guide about when to book flights. But you might have better price luck thinking less about a day of the week to search for tickets and more about how far in advance of your trip to book. When is the best time to buy plane tickets?

Getting a well-priced airline ticket often depends on how far in advance you book, the time of year you travel, and where you plan to visit. There's different guidance around when to buy plane tickets for traveling domestically vs. internationally.

Getting a well-priced airline ticket often depends on how far in advance you book, the time of year you travel, and where you plan to visit. There's different guidance around when to buy plane tickets for traveling domestically vs. internationally.

The best time to book an international flight

For international flights, consider aiming to buy at least 6 months in advance. According to the Expedia report, travelers who booked international airfare 6 months ahead saved about 10% compared to those who bought tickets within 2 months of their travel date.2

CheapAir, which analyzed 917 million flights for its 2023 Annual Airfare Study, suggests an even earlier purchase date. Flights to most international destinations across continents tend to be cheapest 10 months in advance of travel dates.3

The best time to book a domestic flight

It's a little harder to pinpoint the ideal booking range for traveling within the US. Albertynas suggests searching for tickets between 3 weeks and 3 months in advance of your trip. That's when airlines tend to release a limited number of discounted seats. Expedia agrees and adds that booking too early—more than 113 days in advance, specifically—could cost you more.4

Booking at the last minute could also cost you. Flights booked within 2 weeks of the travel date often cost more because you're likely to be competing with business travelers for whatever hasn't been scooped up. Keep in mind that the season you fly affects your best buying window too. According to CheapAir, here's when to find the lowest fares by travel season.

  • Spring: 87 days in advance
  • Summer: 182 days in advance
  • Fall: 49 days in advance
  • Winter: 26 days in advance (but holiday travel dates might call for earlier booking)5

If you know your travel plans well in advance, you could try to book when some deals might be offered, which is often when tickets are initially released. That happens about 11 months ahead of the departure date, says Albertynas.

Ways to save the next time you buy flights

  • Embrace flexibility about when you fly. If a low-cost ticket is your ultimate goal, keep an open mind about your travel dates. Be flexible about the month you visit—February is generally the cheapest month to fly, according to CheapAir. As for the days of the week you fly, midweek departures are generally lower priced than high-traffic weekend days, including Friday. In the CheapAir study, they revealed that flying on Wednesday saves you nearly $100 compared to flying on Sunday.6 That means you could save if you plan a week of PTO for, say, Wednesday to Wednesday rather than Monday to Friday. You also could save if you fly when travelers are generally less jazzed about getting on a plane—very early in the day and late at night.
  • Embrace flexibility about how you fly. Unless you're aiming to use or earn miles or other perks from a particular airline, it might be worth it to be open about which carrier you choose. If you live near multiple airports, you also could spend less on airfare by considering flights to and from all of those airports instead of only the most convenient one. Just make sure to factor in costs for getting to and from the airport—a flight is only a good deal if you don't have to spend much more on a cab or where it's more expensive to park your own car.
  • Use price-monitoring tools. Let automated price trackers do the hard work for you. Many websites source ticket costs from multiple airlines and allow you to set alerts for low fares to and from specific locations and even for specific dates. Just make sure you open the emails flagging price moves as soon as they come in so you can snag a deal when it hits.
  • Keep an eye on prices after you buy. Many airlines have policies honoring cheaper fares you might find shortly after purchasing. Before you book with a particular airline, investigate any rules they have about price adjustments. You might be able to get a refund or a travel credit if you come across a cheaper ticket and report it through the proper channels. Look into what price protection your credit card might offer too.
